Great Britain's card states gain two fighters OR 1 free repair.
What does 1 free repair mean ? You can repair 1 point of damage or you can trigger a repair like the main board space and repair three points of damage ??
Any help would be appreciated !!
I interpreted it as repair one point of damage. No other card references an action on the main board in such a fashion. Compare the text with Japan's power that explicitly mentions activating an air strike.
